<p>我今天写了这个示例代码,来测试一些东西……您可能会发现它也很有用。这假设您有权执行S3函数或列出特定的bucket:</p>
<pre><code>import boto3
import time
import sys
print ("S3 Listing at %s" % time.ctime())
s3 = boto3.client('s3');
def showSingleBucket( bucketName ):
"Displays the contents of a single bucket"
if ( len(bucketName) == 0 ):
print ("bucket name not provided, listing all buckets....")
time.sleep(8)
else:
print ("Bucket Name provided is: %s" % bucketName)
s3bucket = boto3.resource('s3')
my_bucket = s3bucket.Bucket(bucketName)
for object in my_bucket.objects.all():
print(object.key)
return
def showAllBuckets():
"Displays the contents of S3 for the current account"
try:
# Call S3 to list current buckets
response = s3.list_buckets()
for bucket in response['Buckets']:
print (bucket['Name'])
except ClientError as e:
print("The bucket does not exist, choose how to deal with it or raise the exception: "+e)
return
if ( len(sys.argv[1:]) != 0 ):
showSingleBucket(''.join(sys.argv[1]))
else:
showAllBuckets()
</code></pre>
